Application filed August at, 1920. Serial No. 6,70? K To all whom it mayconcern;

Be it known that 1, ELIAS ANDRnAsnN SoHMm'r, residing at No. 123Vesterbrogade,

'1 Copenhagen, Denmark, have invented certain new and usefulImprovements in and Relating to lt fachines for Washing Bottles, ofwhich the following is a specification.

This invention relates to machines for washing bottles. I

The'object of the invention is to provide an improved machine wherebysafe and perfeet cleansing of bottles may be efit'ected without the useof brushes or the like.

According to the invention the bottles after having been soaked andfilled with warm water, are suddenly exposed to a blast of highlycompressed air which ejects the water and impurities,whereupon thebottles are'again filled with warm water and finally emptled and'rinsedwith cold water.

The inventionis illustrated in the accompanying drawings, according toone form of machine. r r p Figure 1 shows a vertical longitudinalsectionof the machine on the line 1-1 of Figure 3.- r

Figure 2 is a horizontal longitudinal section on the line 11-11 ofFigure l, 1

Figure 3 is a vertical section on the line 111-1][][ in Figure 1. l

Fig.- 4: is a horizontal section. on the line 4- 1 of Fig. 2; i

Fig. 5 is an elevation of the machine at the bottle receiving end;

Fig. '6 is an elevation. of the end of the machine from which thebottles are discharged; and,

Figs. 7 and 8 are top plan views of the a right and left hand portionsof the machine,

respectively. I

Referring to the drawing, 1 is a tankin which is fitted an endlessconveying band consisting ,of two roller chains 2 'and of a ftll jointedbottle conveyer mounted between the chains. =The conveyer consists ofnarrow.

pieces 4t hinged together by bolts 3and with funnel formed holes 5 forreceiving the bottles.

The conveyer passes over a'chain wheel '6 at oneend of the tank 1 andover two chain wheels 7 and 8 n1ounted below each otherat the other endofthe tank, the upper edge of the chain wheel 7 being higher than theupper edge of the chainwheel 6 in such way shaft 20.

At one end of the machine (see the left two armed lever 12, 13, theother end of which is fitted with a pawl 14 co-operating with a pawldisc 15 applied onthe shaft 16 of the wheel 7. I

The shaft 17 is rotated by means of a toothed gearing 21 from themain'shaft' 19 driven by a spur wheel 18 which shaft by another toothedgearing 22 turns-another on Figure 1) a tray'2 3 is fitted in such waythat each time the' baihd is displaced, it will be turned from theposition shown in Figure 1 into a'sloping position, whereby one row ofbottles placed. with their necks fore most ,on the tray will glide intoa" corresponding row of receiving funnels 5 in a link piece a. Thismovement of the tray 23' is due to a lever mechanism 24:, 25, 26, 27, 28moved by the shaft 20. i

From the same shaft 20 a corresponding row of expulsion devices 33 ismoved over.

a lever mechanism 29, 30,31, 32, which isfitted on a frame 341.

Outside these expulsion devices is a tray 35, which likewise can betilted by a levermechanism 36, 37 which is moved fromra camdisc 38on'the shaft. From ai compressor 39 with air tank 40, a pipe 4:1 conveyscompressed air to a row of air nozzles 42.-

Theseare connected with the pipe llby air hose a3 and are fitted insleeves 414:, which are lifted by the lever mechanism 4L5,

416 from a cam 50 on the shaft 20. [The conical lower ends 51 of thesleeves M in duev time by their own weight pass down over he bottles,and the nozzles 12, when pressed downto the position shown in Fig. 2will enter the neck-of the bottle. Finally in the pipe systemy al, 413 aspring-loaded valve is fitted, which is not shown in the drawing butwhichgfrom some moving member of ltlll the machine, for instance, thelever 45, is to their'plaoes, partly by spring 53, partly opened at themoment when the nozzles 42 by'a two-armed lever 54,55 moved by a camhave entered the bottles. 8-
